Fixed guide rails lv are secured to the top plate' of the machine 'in Vthe usual-manner 4 and are grooved onf opposite faces-.thereof as Vindicatedgat 2 to`y provide raee-Way's.for-c0- operating anti-friction halls or rollers 3.

These' rollers are receved in opposite grooved faces' 4 in a transverse'bar 5'Which,

with the forwardly projecting end bars 6 and 7, constitute -the platen Aframe" or c'arriage'that 'is supportedvon the anti-friction halls orfrollers'- for transverse vmovement aci-oss the top plate of theniachine in the usual' manner', it being'understood that the l* 'usual' step-fby-step letter spacing or carriage feed mechanism. (no't'shown) isf-employed to control 'the .carriage in its feedvfinovement across the top plate. I

A rotative cylindrical platen 8 is' mounted upon a platen' shaft QWliich extends through and'vis jouinaled inbearing sleeves 10 and 11' received 'in openings in the endbars 7 and '6 respectively of the carriage and secured thereinlbyset s'creivs l2; The platen :is connectedjat theI left-hand end portion thereof to the platenshaft by a: `setl screw 11-3' that passes throughy a. threaded 'opening' in Va. sleeveor hiib 14l formedgon the left-hand .platen lhead `15. The inner end of the screwv 13 hcars against" the;l platen shaft/ and thus 'connects the'platen tothe shaft. lThe-platen head v15 is formed. With 'line spacing 'ratchet 'pa'. wl 17 cooperates.' 'A spring-pressed roller detent .1 8 bears against'the' teetho'f thedine spacing ii-'heel'to` prevent'an accidc'ntal overthrow' off the platen" and to properly positioii. the platenat each spacing move- 'teeth `216 with which the' usual yline'i'spacing v direction.

movement of the platen and shapt in one The yopposite endof the platen g shaft is pi vided with a finger wheel- 2l secured in `111e usual manner tov the platen shaftby a screw 22. The right-hand platen jhead 23 is' secured tothe core of the platen by wood screws 24.111 the usual manner and platen head the outer right-hand tace of the is iiush with the rubber sheath o as shown in Fig. 1.

A disk 25, shown in detail-in Fig. 2,is

the platen provided with openii'igs 26 wl'iichare adapt-` f `'ed to register with corresponding openings in the right-.handbplaten head 23. Rivets 27 unite the disk and the platen head 23. The disk 25 has a central opening 28 therein through which a hub 29 on the right-hand platen vhead extends, the opening 28 being of greater diameter than the liub to provide an annular chainberror recess'in which one end of an expansion spring 291 is. received.

A Vseries of circularly arrangedopeningsBO is provided in the disk 25, the number of the A'openings corresponding-to the'number of line spacing ratchet teeth'l provided on the line spacing wheel. The hub 29 of the-rigl'itf hand platen head has a .cut-out 31 for the .reception of a locking pin or feather 32 sccured to the platen shaft and extending lat- A crally therefrom so as to connect the platen shaft and right-hand platenhead to turn together, but permitting the shaft to be withdrawn from the' head. A stop-carrying Hear or wheel 33 has a laterally projecting liub 34 'on one side thereof. The centra-l opening 35 in the: stop-carrying wheel isof adiaineter: that corresponds essentially to the .i -hand face of the gear.v33 for purposes will hereinafterfap ear.` A disk 42 is provided with 'a central openinner face of the stop-carrying wheel 33 and at its opposite end against the out-erA face .of the rightLhand platen head, the spring being received in' the opening or annular recess formed between the hub 29 and the disk-.25.

The gear 33 has astop 37 whiclrprojects, l-w 55 'i which is riveted tothe gear as indicatedat r`38.1in Figs. 341ml 4.-A locking.pin' 39 isj driven and secured by a drive fit irralined'4 laterally from-the outer Aface thereof' and openings in-thc' sto'p and gear, and'projects I at one end 40 to the right of the stop 3 7fand at the other end 41 tothe left ofthe' letting 43Hto receive the boss or enlargement 44 on the right-hand endbar 6 of the platen .frame or.v carriage so that the body of the disk `42 may bear against the innerf face of said end bar, towhi'ch it is secured byserews 45 andat. These screws pass freely through openings in the right-hand end bar and are received at their threaded .ends in tapped ries an inwardly projecting stop 42" secured thereto in an 42 has a cy indricul housingl v47 secured thereto, the housing# vextending inwardly from the -disk and surrounding the stopcarrying gear 33 and the associated parts. The housing 47 has va slot 48 eutending around it for a( considerable distano as indicatcd in'Fig. 8,and indices 49ft'orma l line space indicating scale along one edge of the slot. m f

From an inspection of Fig. 5 it will be seen that a segmental stop carrier 50 is pro- `vided with a stop land a supporting ring 52-is secured to the stop by rivets 53, The segmental carrier has a tapped opening in Vone end thercof."` The supporting ring or open'ings'in the disk' 42.

A thuinb screw .'.5 .extends through the l slot 48 in .the cylindrical housing and takes at its threaded. endin thetapped opening 54 in t-hestopl carrier, a 'shoulder on the thumb screw binding against the outer -tace of the cylindrical housing to secure, the stop 51 and its carrier in any'position to which they may be adjusted aroundthe axis ofthe platen. The disk42 is provided with a single opening '56 therein for eoperation with the end -vt() of the locking'pinwhen the parts are in .the normal positions indicated in Fig. 3. A

sliding inmfgment of the stop-carrying gear .33 .toward the platen will, however, displace V'the end 40 o f the'pi'n from the opening 5G and thus disconnect or unclutchA the stoprarrying gear from the fixed housing and' from the carriageto which 1t is normally.

The pressure of 'the springi)1 then rbecomes efective-to slidethe gear33 outwardly in `the'dire'ction 8F of' the axis of the platen to automatically e'li'ect a. disconnection between vthe gears 33' and 57,'a't the saine time disconnecting the ear 33 from the platen.Avi 1 1,1' The sizes of the stops 42, and'laie" 90 such that; the stop 37 in its4 rotative inov l.

-nient is adapted to coactfwith the relatively fixed stops'e12 and 51, notwithstanding the shitting ofthe gear 33 in the direction of the axis fof the-platen to render the gear 33 95 operative. It will be understood that the .stop 112a is a fixed stop which always remains in the saine position, whereas thestop 51 is adjustable in a circular path around the axis ofthe platen and'is secured in its adjusted position. by the thumb screw 55. VThese two stops extend into the path of movement of the stop 37 around the ajxisgof the platen andv arrest the platen` iiidits back-wardand forward rotations. 'i

Iiiorder to setthe stop 51 inthe first in-V stance, it merely necessary to introduce carrier 50 moved lby lthe thumb screw until 'the A`lat-ter registers with the index 26, :ind the' thumb screw is then tightened tov seeurethe adj ustable stop 51 in' the position lto' lwhich-it .ha'sbeen set. The roperator -inay -thenfproceed to writegtheini'oice,1a.'copy thereof vbeing duplicated' on the record sheet through the interposedcarbon. When theV invoice has been completed the operator will .effect-a two o r three line space movement of 13e 4: I y990,307l

the platen, by the usuali line spacing mecha.

' msm, in order to provide a proper spacing between the last written item reproduced on the record sheet andthe first line of the next :record to be reproduced-thereon, thus providing pro er` spacing between successive copies on t c record sheet. i The operator may then remove the invoice sheet without;` disturbing the -carbcirand record sheets..

The writing of the last itemvon the invoice sheet left lthe earriage'near-the left-hand(- end of its travel and it. should be allowed t to remain in this position and pressure is exerted on the finger piece 73 to move the gear 2153 into mesh with its companion gear 57., The operator may then move thecarriage to the right, thus effecting a rotation` of -the gear through the'intermediate trainv .of rearing between said gear 33 and the.

fixed rack (58, the various parts -`at this time' moving in the directionsjof the arrows in' Figs. t3 and 9. This is effective to turn the platen back-wardly until the stop V37 travels trom. the position shown in Fig. 9 adjacentto the fixed stop 42, until it isarrested by the adjustable stop 51. As soon as the platen starts torotate-the operatorinay reinoiv'erpressure on the finger piece 7 3 and the locking pin l1() bearing against the inner face of the` disk 4:2 will maintain the gear 33 in proper engagement with Atliefdisk 25 fixed to the right-hand platen head`.a.nd will'4 maintain the gears and 57 in mesh.l The rearward or backward rotation of the platen* thus produced is effective to turn the platen the requisite distance to receive a new 1nroiee. sheet which may now be introduced intothe'machine. The carriage maynow be ,moved from right -to leftto effect a brought into register with its opening 56' and the pressureot the spring 29 is effective to restorethe gear 33 to normal position where the locking pin 40 is received in its opening` 5G and .a disengagement between the gears 3? and 57 is automaticallyi effected and a 'further movement of the` c ar,'f' Y ringe at this Itime is in'efl'eetivc toproduce" a rotat ion iofthev platen. The carriage .may then beinoved to? the proper letter' space position to begin writing the first line and the operatoria-ay 'proceed with the' writing of the'invoice'sheebin the ordinary. man? .may lie-'adjusted from, say, the twenty-t ner, the writingl beingl reproduced through the interposed carbon on the record sheet.

'The operation lmay thus. be continued indefinitely until the record 'sheet is filled when .new recor(1 ,-carbon and-invoice sheets may be introduced into Atlie", machines as before. f

lVhile IA have. shown in the' resent instance a constructionwherein e` stop1 51 'ird to` thetwenty-eighthline space position,

" which is ordinarily sufiicient for the average condensed' reeord'work, affording as 1t does nearly a com lete rotation of the platen, nevertheless tie'` parts may be constructed and arranged to afford, a greater variation or range of adjustment of the stop 51 if desired and various changes may' be made without departing from my invention.

. Fromftlie foregoing descriptionit will be understood that the stops 37, 42 and 51 constitute means for determining the extent of backward and, forward rotations of the jplaten, although from the broadaspects of my invention any determining means ma bc employed. Itwill also befseen that'eac of the gears of the train between the' rack vG8 .andthe gear 57 receives a. rotation in one direction when the carriage is moved in one direction and receives a reverse rotation when the carriage is moved in the opposite direction, and that the finger piece 73 is operable atA will to operatively connect the platen with the gear 57 and thus render the 'movement 'of the carriage effective to rotatr the platen-either forwardly or backwardly depending on the ldirection of movement of the carriage.'
